Student disclosures of fraudulent practice in school laboratories

The debate about the inclusion of laboratory practicals in the school curriculum is continued in this paper which reports on fraudulent practice by students. One of the widely accepted goals of school laboratory practicals is to teach students about the nature of scientific inquiry. This paper reports how student disclosures of their actual practice in school laboratories is at odds with such a goal. We identify and define the student practice of “fudging” which involves faking, fabricating, or stealing data. Five types of fudging behaviour are described. The factors contributing to and the motivations for such behaviour are also identified.     

Feeding ecology and laboratory predatory behavior toward live and artificial moving prey in seven rodent species

The present research related the feeding ecology of seven rodent species to the reactions of laboratory-reared and prey-inexperienced members of each species both to live prey and to an artificial moving stimulus predicting food pellets. Feeding ecology was determined by the degree of carnivory, based on reported stomach contents and observations of feeding. Experiment 1 assessed predatory reactions to a live cricket placed in each animal’s home cage. Killing and latency of eating the cricket were directly related to the degree of reported carnivory on moderately fast-moving arthropods. Experiment 2 examined behavior toward a rolling ball bearing that predicted delivery of food. Average percentages of trials with approach or contact of the bearing, and the conditional probability of a mouth contact were all positively related to the degree of reported carnivory and to cricket predation in Experiment 1. In addition, the topography of ball bearing contact for a species often resembled its topography of cricket contact. We conclude that (1) rodent predatory behavior can be studied in the laboratory using appropriate artificial stimuli and prey-inexperienced subjects, and (2) the predatory behavior of a species is based on underlying appetitive organization related to carnivory, including differential sensitivity to stimulus movement, motor preorganization, and susceptibility to conditioning. This appetitive organization appears to influence responding to both live and artificial prey.     

Student experiences of NAPLAN: sharing insights from two school sites

This paper provides insight into middle school students’ perceptions and reactions to their participation in the Australian National Assessment Program—Literacy and Numeracy (NAPLAN). A case study was conducted over 10 months at two Queensland schools with different approaches to NAPLAN implementation. Student voice was elicited via focus groups and 35 students provided drawings and words describing their experience in four stages: preparing, sitting, completing and receiving their results. Thematic content analysis of the textual data and trait and holistic coding of the visual data revealed five themes and suggests that the approach adopted by the school may impact on students’ NAPLAN experiences. This study privileges student voice and enables access to student experiences as they participate in a testing regime which is now a feature of the Australian school assessment landscape.     

The determinants of random choice

The purpose of the present experiment was to describe a pattern of reinforcement sufficient to produce an unpredictable pattern of choice response by rats. On each trial two levers were inserted into an experimental chamber. If the reinforcement was always contingent upon single alternation (a simple pattern), Ss learned to alternate at significantly better than chance level; if reinforcement was contingent upon alternation on 50% of the trials (an insoluble pattern), Ss developed a position preference. To produce apparently random responding, the less preferred response (an alternation) was differentially reinforced on 75% of the trials. A simple stochastic model adequately described the results.     

Case study: One teacher’s odyssey through resistance and fear

Conclusion As a teacher educator in this multi-dimensional information age, I must model instructional methods and develop activities in my classrooms which help future teachers understand that technology based instruction is no longer an option. It is a requirement. My instruction must help students rethink their prior classroom knowledge and experience and focus on how they can, now and in the future, teach their students using this new software and methodology and enable them to become literate citizens in a global world.
